Subject: [PATCH 1/2] Fix the output for no_args_is_help=True
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since typer 0.16.0, running a CLI with the no_args_is_help feature
enabled displays an error block, e.g. for my application:

 Usage: myapp [OPTIONS] COMMAND [ARGS]...

 This is the CLI for my app

╭─ Options ─────────────────────────────────────────────────────────╮
│ --verbose  -v        Use multiple times for more verbosity.       │
│ --help               Show this message and exit.                  │
╰───────────────────────────────────────────────────────────────────╯
╭─ Commands ────────────────────────────────────────────────────────╮
│ version   Show application version.                               │
│ run       Start the application.                                  │
╰───────────────────────────────────────────────────────────────────╯
Usage: authsync [OPTIONS] COMMAND [ARGS]...
Try 'authsync --help' for help.
╭─ Error ───────────────────────────────────────────────────────────╮
│                                                                   │
╰───────────────────────────────────────────────────────────────────╯

The patch from the PR suppresses the duplicate Usage: info and the Error
output block, in case the processed exception is a NoArgsIsHelperror.
